Qt-Based Software System Design for Lower Limb Exoskeleton Safety Testing Platform

To achieve the visualization of the operational status data of the lower limb exoskeleton safety testing platform, an upper computer software based on the cross-platform Qt graphic library framework was designed in the object-oriented C++ programming language; the software decodes and analyses the received motion data, the main page implements functionalities including the display of motion parameter detection data, plantar pressure data, z-axis vertical center of mass displacement changes, and the final presentation of safety testing results. Firstly, the structure and principle of the self-designed lower limb exoskeleton safety test hardware platform and the software implementation process are introduced; then the functions of the upper computer software and the design and implementation process are introduced; finally, the lower limb exoskeleton safety test platform is used as an experimental object to validate the effectiveness of the designed upper computer software.
